  • Applications

    Neopentyl glycol dimethacrylate (CAS 1985-51-9) is a bifunctional methacrylate monomer widely used as a crosslinking agent in UV-curable coatings and inks, enabling durable, flexible networks. It also serves as a reactive diluent that adjusts viscosity and participates in free-radical polymerization in acrylate formulations for coatings, adhesives, and sealants. In polymer resins, it acts as a building block for specialty acrylate polymers to improve mechanical and chemical resistance. In electronics and optics, it is used in UV-curable encapsulants and protective coatings for components and assemblies.
